This invention relates to a multiple knockdown box, and the principal object is to provide knock-down parts of relatively uniform shape and locking means in various sizes so that boxes of various sizes with removable partitionstherein that can be formed from the parts by assembling them in proper orderand detachably securing them together as planned.

One feature of this invention consists in the process of forming multiform knock-down boxes for packing and other purposes, varying in size,

dimensions and interior arrangements, from a set of box parts, similar box parts being uniform in size and shape, and said box parts provided l5 with means for interlocking them together in any position in the box as desired.

Another feature of the invention consists in providing a single set of box parts, similar parts being uniform in size and shape, and said parts being provided with uniform interlocking means whereby from said set of parts arpacking box may be quickly assembled or built in any desired size or form suitable for receiving a desired -article or number of articles of merchandise.

These parts are such that they can be readily united to form any desired size or shape of packing box without the use of nails, brads or metal bands. Y

A feature of invention is shown in providing shipping boxes that include relatively few simple uniform parts that can be readily transported and cheaply stored, and from which packing boxes of any size or shape desired may be readily assembled and used, and since same is free from nails, brads and metal bands, they kcan be readily opened and knocked down and restored for use again. p

rIhe full nature of the foregoing and other features of the invention will more fully appear from the accompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a perspective view of a packing box made in accordance with said invention, parts'being broken away as indicated to show my removable partitions. plan view of one ofthe corner block posts shown in Fig. Land an interlocking adjacent Vportion of the wall of the box, the latter being partly broken away. Fig. 3 is a vertical section through the box on the line 3 3 of Fig. 2, the central portion, however, being broken away, as shown.

Fig. Ll is a perspective view of the lower portion of one of the rods for securing the corner block posts together. Fig. 5 is a fragmental elevation Fig. 2 is a (o1. zii- 12) of an attachment for the inside surface of a side wall with partition locking means and one partition being atached thereto and` partly shown in vertical section.y Fig. 6 is a fragmental plan view of an attachment for a side wall, showing E@ a partition locking means and a portion of a partition in place therein. Fig. 7 is an elevation of the compartment partition with partition locking tongues and one partition associated therewith and being in vertical section, the compart- 65, ment partition being partly broken away. Fig. 8 is a vertical section on the line 8 8 of Fig. 7. Fig. 9 is a fragmental plan view of a horizontal partition detaohably connected at its ends to two vertical partitions, showing how the tongues of '79. thefoimer are connected to the straps of the latter. Fig. l0 is a side elevation of a wall superimposed on another wall and locked therewith for increasing the height of the box, parts being .broken away. Fig. 1l is afragmental vertical 7,5

section on the line 11-11 of Fig. l0. Fig. l2 is a plan View of the center post ofthe box with four vertical partition walls connected therewith, said partition walls being partly broken away.

Fig. 13 is a side elevation of what is shown in 80I Fig. 12, parts being broken away. Figp14 is a plan View of two partsof a side wall united by a connecting post showing how. the side can be extended to enlarge the box, the two parts of the side wall being partly broken away. Fig. `15 is a 85 vertical section on the line 15-15 of Fig. 14, parts being broken away. Fig. 16 is a perspective view of one of the angle reinforcing plates at the end and bottom of the box, the same being partly broken away. Fig..17 is a plan view 9,0 on a small scale of the box-lid formed of sheets of veneer or sheet metal. Fig. 18 is a section on line 18--18 of Fig. 17. Fig. 19 is a plan view of the box lid formed of veneer or sheet metal strips arranged to form a slat top. y Various formsk and combinations of partsv of the packing box constituting this invention obviously may be employed, but a simple form thereof is shown in Fig. 1. There is shown therein a bottom wall 20, side walls 21 end walls 22 100 Ain a rectangular box, and a top 23 and corner rounded so as to receive the rounded portion of the tongue 26, and these tongues and grooves interlock and secure the walls to the corner posts, as stated. The tops and bottoms 20 andV 23, respectively, of the box are secured to the other members of the box by the corner tie rods 30, fragmentally shown in Fig. 4, which extend through a hole 29 in the post, and has its upper end threaded for the nut 130. Each of the posts is provided with nuts 130 so the lid 23 can be detachably secured to the box. These nuts are secured in place by cotter pins 230. The lids or tops 23 can be formed in any suitable way, but preferably they are formed of veneer strips 123 having end plates 223 through which the corner holes 29 are extended for the rods 30, as best shown in Figs. 17, 18 and 19. At the lower end each tie rod has an integral angle plate 31 that reinforces its respective corner of the box as well as aids in supporting the bottom of the box.

The foregoing describes a simpleconstruction of said packing box, but it is to be understood that the invention is not limited to the particular tongue and groove arrangement described and shown, nor to single posts and walls as they can be each used in plural form for enlarging the height of the box, as desired. In such case, however, the tie bars 30 extend entirely through the box from bottom to top.

The ends and bottoms of the box are reinforced, preferably, by the construction shown in Figs. 4 and 16. The angle plate 31 at the lower end of the tie rod 30 is provided with upwardly extending side flanges or angle bars 33 and the reinforcing bar 34 shown in Fig. 16 are placed upon the plate 31 at the lower end of a tie rod 30 and is provided with a hole 35 for the tie rod 30 to extend through and also with an outwardly turned ange or angle member 36 which extends out over the side flanges 33 of said bottom plate 31. The assembled form is shown in Fig. l. l

Suitable vertical and horizontal partitions are provided for in this invention, as seen in Figs l and 9. In the vertical partitions a cross partition 40 is shown connected with the side of walls 21 and a longitudinal partition ,41 connected at one end with said cross partition 40 and at the other with the end wall 22 as best shown in Figs. 1, 5 and 6. For the purpose of removably connecting said partitions, the cross partition 40 is provided with enlarged lateral edge beads 42 adapted to be vertically introduced between pairs of tongues 43 that are punched out of the sides of the metal reinforcing strips 125 as seen in Figs. 1, 5 and 6.

In Fig. 1 there are three of such reinforcing metal strips 125, one in the bottom, one in the top, and one at an intermediate position, but the number thereof may be increased as desired.

The connecting means for one end of the longitudinal partition 41 is indicated in Fig. 1. The cross partition 40 is provided with vertically aligned rows of straps 45 that are punched out of the partition into which the tongues 46 are extended, and these tongues are integral with and bent at right angles to the ends of the longitudinal partition 41.

'I'he partitions 40 and 41 may be multiplied as desired and have the desired dimensions, and also the desired removable connecting means in the construction of a box requiring them.

The horizontal partition plates 50, as seen in Fig. 9, are also provided in the box and may be .or walls.

nFor extending the side walls of the box the means shown in Fig. 14 is employed wherein there is a post 62 with opposite grooves 27 therein adapted to receive the tongues 26 of the two parts of the side wall 21 that are in alinenent with each other. Said post has a hole 29 for receiving tiebar 30similar to the other post.

In operation the parts of my multiform box are constructed, arranged and assembled or knocked down as hereinbefore fully described.
